Impersonation in MapR

Describes impersonation in MapR, which allows centralized control of access to
resources in the MapR-FS, MapR-DB, and MapR-ES.

Also known as identity assertion, impersonation is one user (authorized to impersonate another) or the mapr super user
accessing data and submitting jobs on behalf of another user. Implementing impersonation
provides authoritative, end-to-end security for your MapR installation, independent of remote
authentication and security mechanisms that control user access to application features.

To implement impersonation in MapR, there are both MapR core and ecosystem component
requirements that must be met as well as requirements at the application development level.
These requirements are described in Access Control
and Impersonation in MapR.
